Stand-in Beau Ryan said he had been texting the shock jock overnight though.

'I don’t know what Kyle is doing,' Ryan added.

The latest radio ratings survey, the fifth this year, recorded that Sandilands and Henderson’s KIIS FM show dropped 1.7 percentage points to an overall share of 9.3 per cent. Jonesy and Amanda scored 10.3 per cent to take the coveted top spot.
